JOSEPH BUTLER, 055' AlUCKLA-ND, NEW ZEALAND, ASSIGNOR T0 KAURI 'TIMBER COIVIBANY LIMITED, OF MELBOURNE VICTORIA, AUSTRALIA., 1i-COMPANY 0F VIC- Tonia.

To @ZZ 107mmt may yconcern.'

vBe it known that I, ',Iosnrrr BUTLER, a

subject of the King of Great Britain and Ireland, and a resident of the Provincial District of Auckland, in the Dominion ofk New Zealand, have invented a certain new and useful Improved lVooden Panel, of which the following isa specifica-tion.

This invention relates to an improved wooden panel for use in the manufacture of butter and other boxes or cases and for various other purposes to which the panel may be suited.

The object of the invention is to provide a composite panel which is cheap to manufacture and economical in material and permits of thin wooden sheets or veneers being used to form a strong light and efficient panel having a two ply centre and a thickcned marginal portion for nailing purposes.

But in order that this invention may be better understood reference will now be made to the accompanying sheet of drawings which are to be taken as part of this speciiication and read herewith Figure l is a section of a panel constructed in accordance with the invention.

Figure 2 shows a modification.

Figure 3 is a side view of the panel seen in Figure l, a portion being broken away to show the interior of the panel.

Figure 4 is a part sectional elevation of a box constructed from the improved panels.

A panel according to the invention includes a frame 2 of rectangular or other desired formation. This frame may be made up of a series of wooden strips or battens of the desired thickness and size, these members being united at their ends by any suitable means embodying either an angular or other form of joint 3.

Secured to the opposite sides of the frame 2 are two veneers or thin wooden sheets 4 and 5 which are coated on their inner or opposed surfaces with a suitable adhesive substance such as glue or the like indicated at 6. These two veneers are forced against the opposite sides of the frame 2 so that their marginal portions adhere to the frame as in Figures l and 2.

As seen in Figure l which illustrates the preferred embodiment of the invention, one of the veneers', indicated at 4:, is 'Hat or plain whilst the main central portion 7 of Specification of Letters Patent.

the other veneer 5 is indented or impressed inwardly against the opposite veneer by any suitable means for exerting pressureon the vveneer to impart the desired contourto it.

That portion of the veneer 5 between the impressedcentral area 7' and the marginal portion is inclined or converges'inwardly as at 8, the angle of inclination being such as to permit of the veneer being shaped under pressurein the manner indicated With-, out fracturing or injuring it. two opposite veneers are being thus forced together under pressure, the frame 2 isv also compressed between the veneers to ensure proper adhesion of the veneers thereto.

Instead of one of the veneers being Hat or plain and the other impressed or indented as in Figure l, both the veneers may Ibe im pressed as in Figure 2 and their central portions 7 secured together by the adhesive 6. Inthis case the two veneers may be impressed to the same depth, equal to half vthe thickness of the frame 2, as in Figure 2, or one of the veneers may be impressed to a greater depth than the other, according to requirements.

In. addition to the adhesive 6, staples or like metallic fasteners 9 may be employed with either of the embodiments shown to secure the abutting center portions ofthe veneers together and also to secure the marginal portions of the veneers to the frame 2.

In attaching the veneers to the frame, they are preferably arranged with their respective grains running in opposite directions to strengthen the structure.`

In forming a box or case from panels as seen in Figure l, the indented or impressed veneer 5 is preferably disposed on the outside of the box so that the fiat or plain veneer on the other side of the panel provides a plain or uninterrupted internal sur\ face for the box, the panels` being arranged as seen in Figure 4; and secured together by nails or the like 10 passing through the thickenedv marginal portions provided by the frames 2 asillustrated.

A panel constructed in accordance with the invention is simple and inexpensive to manufacture and permits of the economic utilization of wood in such a manner as to give maximum strength with minimum weight and expense of material. It will l/Vhilst the` be evident that although the invention is particularly suitable for l making butter boXes and the like, it is not by any means limited thereto but may be employed for various other purposes.

Having now described my invention what I claim as new and desire to secure by Letters Patent is l. A composite panel for packing cases,

comprising a flat, skeleton frame, and outer and inner veneer sheets disposed at their marginal portions against the opposite side faces of said liframe; the outer veneer sheet having a well-defined, liat central area which is impressed inwardly ot' the panel and disposed immediately against and secured directly to the central portion of the inner rveneer sheet, the portion of the outer sheet which-lies between its said marginal and JosErH BUTLER.
